Description
The Austin MegaLynx ATM series SMT power modules are non-isolated DC-DC converters in an industry standard package that can deliver up to 30A of output current with a full load efficiency of 92% at 1.8Vdc output voltage (VIN = 3.3Vdc). These modules operate off an input voltage from 2.7 to 4.0Vdc and provide an output voltage that is programmable from 0.8 to 2.0Vdc. They have a sequencing feature that enables designers to implement various types of output voltage sequencing when powering multiple modules on the board. Additional features include remote On/Off, adjustable output voltage, remote sense, over current, over temperature protection and active current sharing between modules. RoHS Compliant

October 21, 2009 Austin MegaLynxTM SMT: Non-Isolated DC-DC Power Modules: 2.7 – 4.0Vdc input; 0.8 to 2.0Vdc Output; 30A output current LINEAGE POWER 13 at the SEQ pin is applied. This will result in sinking current in the module if pre-bias voltage is present at the output of the module. When pre-bias immunity during start-up is required, the EZ- SEQUENCETM feature must be disabled. For additional guidelines on using EZ-SEQUENCETM feature of Austin MegaLynx modules, contact the Tyco Power Systems Technical representative for the application note on output voltage sequencing. Active Load Sharing (-P Option) For additional power requirements, the ATM030 series power module is also available with a parallel option. Up to five modules can be configured, in parallel, with active load sharing. Good layout techniques should be observed when using multiple units in parallel. To implement forced load sharing, the following connections should be made:
- The share pins of all units in parallel must be connected together. The path of these connections should be as direct as possible.
- All remote-sense pins should be connected to the power bus at the same point, i.e., connect all the SENSE (+) pins to the (+) side of the bus. Close proximity and directness are necessary for good noise immunity Some special considerations apply for design of converters in parallel operation: When sizing the number of modules required for parallel operation, take note of the fact that current sharing has some tolerance. In addition, under transient condtions such as a dynamic load change and during startup, all converter output currents will not be equal. To allow for such variation and avoid the likelihood of a converter shutting off due to a current overload, the total capacity of the paralleled system should be no more than 75% of the sum of the individual converters. As an example, for a system of four ATM030A0X3-SR converters the parallel, the total current drawn should be less that 75% of 4 x 30A or 90A.
- When sizing the number of modules required for parallel operation, take note of the fact that current sharing has some tolerance. In addition, under transient condtions such as a dynamic load change and during startup, all converter output currents will not be equal. To allow for such variation and avoid the likelihood of a converter shutting off due to a current overload, the total capacity of the paralleled system should be no more than 75% of the sum of the individual converters. As an example, for a system of four ATM030A0X3- SR converters the parallel, the total current drawn should be less that 75% of (4 x 30A) , i.e. less than 90A.
- All modules should be turned on and off together. This is so that all modules come up at the same time avoiding the problem of one converter sourcing current into the other leading to an overcurrent trip condition. To ensure that all modules come up simultaneously, the on/off pins of all paralleled converters should be tied together and the converters enabled and disabled using the on/off pin.
- The share bus is not designed for redundant operation and the system will be non-functional upon failure of one of the unit when multiple units are in parallel. In particular, if one of the converters shuts down during operation, the other converters may also shut down due to their outputs hitting current limit. In such a situation, unless a coordinated restart is ensured, the system may never properly restart since different converters will try to restart at different times causing an overload condition and subsequent shutdown. This situation can be avoided by having an external output voltage monitor circuit that detects a shutdown condition and forces all converters to shut down and restart together. When not using the parallel feature, leave the share pin open.
